Another plotline might be exploring Naruto's past more deeply. Maybe there are secrets about his parents that were never fully revealed in the original. In the fanfiction, he could discover something new about his father's time as Hokage or his mother's Uzumaki heritage that changes his perspective on his own powers and responsibilities.
One common theme is the passing of the torch. Older Naruto is often shown mentoring the younger generation, like how Kakashi mentored him. Another theme is dealing with the scars of past battles, both physical and mental.
In fanfiction, an older Naruto may have a more refined sense of leadership. He has seen more, experienced more battles and political situations. So, he might be more diplomatic in his approach compared to his younger self.
Older Naruto fanfiction often has a more nostalgic feel. It was written when the Naruto series was still fresh in people's minds, so the authors were really exploring the initial concepts and characters. Many of them focus on filling in the gaps in the original story, like Naruto's early years or what happened between certain arcs. They also tend to be more influenced by the early art style and themes of the anime.
In such fanfictions, the plot might revolve around them teaming up for a mission. Maybe it's a mission that requires Naruto's brute strength and Hanabi's precision and knowledge of the Hyuga techniques. This could lead to them growing closer as they face challenges together. Their interactions during the mission, like Naruto making Hanabi laugh with his silly antics or Hanabi impressing Naruto with her skills, would be interesting to explore.
Well, in some fanfictions, Naruto might be shown as older by having him achieve higher ranks earlier. For example, he could become Hokage before Kakashi in the fan - made story. This would signify his more advanced position and potentially imply his older status in terms of experience and leadership.
One popular 'naruto older naruto fanfiction' is 'The Legacy of Naruto'. It shows an older Naruto dealing with new threats to the Hidden Leaf. Another great one could be 'Naruto: The Elder Sage' where he has mastered new jutsus and is guiding the new generation.
The older brother in the fanfiction might be a character with a tragic past. For example, he could have been experimented on by Orochimaru and gained some strange powers as a result. And he returns to the village later to protect Naruto from the threats that are coming towards him.
Well, in this fanfiction idea, Naruto being Sona's older brother could bring a whole new dynamic. Maybe Naruto's protective nature would extend to Sona. He could teach her some of his ninja skills and values like never giving up. It could also create interesting interactions with the other characters in their respective universes. For example, how would the devils in Sona's world react to Naruto's presence? And how would Naruto handle the political aspects of Sona's world which are quite different from his own ninja village politics.
There could be. Fanfiction writers like to explore different 'what - if' scenarios. Since Naruto and Kushina have a strong connection in the original series, some writers might be intrigued by the idea of reversing their relationship in a fictional context. But it goes against the established lore of the main Naruto storyline.
